Can anyone help me figure out what’s up with my Goni. Was super happy 6” polyps with giant heads. For the last few months it has retracted. There’s a brown substance on it that doesn’t seem to be spreading but it’s closed up most in that area. Water parameters haven’t changed. Alk 8.5 controlled via trident. Nitrates 10 - 15 phosphate .08 to .12.
